HAND TOOL Filed Feb. '7, 19150 Patented May 5, 1931 ATE? FFICE FRED J. CLEMENS, OF EAST HAVEN, CONNECTICUT, ASSIGNOB TO THE WILLIAM SCHOLL- HORN COMPANY, OF NEW HAVEN, CONNECTICUT HAN ID TOOL Application filed February 7, 1930.

My invention relates to a hand tool, and more especially to a belt plier suitable for cutting off a length of round or other belting and piercing a hole near the end of the same for the reception of a hook or link.

Pliers for cutting and piercing belting are well known in the prior art. For example, the patent to Bernard No. 488,785 shows a belt plier in which the cutting and piercing operations are performed simultaneously. It is in general an object of the present inven tion to provide a relatively simple form of belt plier in which the cutting and piercing operations may be carried out more eficiently than has previously been possible.

In a more specific aspect, it is an object of the invention to provide a belt plier having a cutter and an arrangement for supporting the belt at either side of the cutter during the cutting operation.

A feature of the invention resides in a novel form of cutter and a novel arrangement for attaching the cutter to its jaw.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the drawings Fig. 1 is a plan view of a belt plier according to my invention Fig. 2 is a view similar to Fig. 1 but partly broken away and showing the jaws of the plier in open position;

Fig. 3 is a sectional view along line 3-3 of Fig.

Fig. 4 is a sectional view along line 44 of Fig. 2, and

Fig. 5 is a sectional View along line 55 of Fig. 1.

Referring now to the drawings in which I have illustrated my invention by showing a preferred embodiment of the same, the reference numeral indicates in general the improved belt pliers which, in this instance, take the form of the open throat and parallel jaws Serial No. 426,588.

of the pliers of the Bernard patent referred to above, and comprise, generally speaking, jaws 11 and 12 and operating handles 13 and 14. Handles 13 and 14 are formed in the usual manner out of sheet material and are hingedly connected together by rivets 15 and 16, and to jaws 11 and 12 by means of bolts 17. Jaws 11 and 12 are maintained parallel to one another as the pliers are opened and closed by means of pins 18 and 19, mounted in handles 13 and 14, and passing through slots 20 and 21 in the ends of jaws 11 and 12.

On their opposing faces 22 and 23, jaws 11 and 12 are provided with oppositely disposed transversely extending semi-cylindrical grooves 24 and 25, groove 25 being intersected transversely by a narrow semi-cylindrical slot 26 in which the convex lower edge 27 of cutter 28 is received, while groove 24 is intersected transversely by a narrow semicylindrical slot 29 into which the convex cutting edge 30 of cutter 28 passes as the pliers are closed. Cutter 28 isheld in slot 26 by means of screws 31 and 32, which pass through jaw 12 and bearing against the cutter 28, forcethe latter against face 33 of slot 26, face 33 being so positioned that the cutting edge 30 passes freely into slot 29 as the pliers are closed, slot 29 being of greater width than the thickness of cutter 28.

In order that the cutter 28 may be properly positioned in slot 26 and held against movement out of the slot, the cutter is provided with tapered holes 34and 35 into which the conicalends 36 of screws 31 and 32 pass, the jaw 12 being counterbored at 37 to provide clearance for the conical ends-36.

In operation, a belt is supported in groove 24 and the cutter 28 forced against and through the belt as the jaws 11 and 12 are closed. The belt is supported at either side of the cutter during the operation of the pliers and the convex cutting edge tends to force the belt towards the bottom of roove 24. j

Between cutter 28 and ad acent end of 99 handle 13, jaw 12 is provided with a threaded opening 38 extending towards jaw 11, threaded opening 38 serving to support a hollow punch 39 which is threaded at 40 for reception in opening 38, and which is provided with a sharpened cutting edge 4:1 adapted to engage a belt supported in transversely extending cylindrical opening 42 in jaw 11. Jaw 11 is provided with an opening 4-3 opposite punch 39, through which the latter passes as the pliers are closed. A plug 14: of relatively soft material is mounted in alignment with opening 13 against which the punch 39 abuts when the jaws are closed. In the particular form shown, a semi-cylindrical transversely extending groove l5 in jaw 12 provides clearance for semi-cylindrical projection 46 on jaw 11, opening 42 being partly in the semi-cylindrical projection and partly in the jaw proper. It will be readily understood that a belt placed in opening 42 will be pierced by punch 39 as the jaws are fully closed.

While I have shown and described a pre ferred embodiment of my invention, it will be understood that it is not to be limited to all of the details shown, but is capable of modification and variation within the spirit of the invention and within the scope of the appended claims.

What I claim is:

1. In a belt plier, a pair of cooperating jaws, a relatively narrow slot in one of said jaws, said slot having a semi-cylindrical bottom edge portion, a cutter mounted in said slot and having an edge portion shaped to lit the bottom edge of the slot, a convex cutting edge on said cutter extending towards the other jaw, and an opening in the other jaw in which the cutter is received when the jaws are closed.

2. In a belt plier, a pair of cooperating jaws, oppositely disposed relatively narrow slots in said,jaws,said slots having general- 1y circular bottom edge portions, a cutter shaped to fit and fixedly mounted in one of said slots, said cutter having a cutting edge which is shaped to be received in the other slot when the jaws are closed.

3. In a belt plier, a pair of cooperating in which the end of the screw is received.

In witness whereof, I have hereunto set my hand this 3 day of Feb, 1930.

jaws, one of said jaws being provided with a slot having a convex bottom edge portion, a cutter mounted in the slot and extending towards the other jaw, said cutter having a convex inner edge shaped to lit the bottom edge of the slot, and means for forcing the cutter against one of the side edges of the slot to hold the cutter therein.

4. In a belt plier, a pair of cooperating jaws, a slot in one of said jaws, a cutter in said slot and a screw for holding said cutter against movement out of said slot, said screw being provided with a conical cutter engaging end, and said cutter being provided with an IHU
